CTI Text Encryption is a lightweight, portable text encryption tool. Its ideal for sending sensitive information via insecure channels (email, online chat, web forums), perhaps from someone elses computer, although you can also use it to save confidential data in files or elsewhere.

The open source program is a tiny download (827KB), a single executable with nothing else attached. Copy the file to a USB stick and its ready to use almost anywhere.

CTI Text Encryptions interface appears a little confusing initially, as it has almost no text labels or prompts. Fortunately its buttons do have tooltips, so hovering the mouse over each one reveals some helpful clues.

The process starts by entering the encryption passwords youd like to use. CTI Text Encryption supports up to four, which means you dont necessarily have to remember garbage like "lF@,%*jwX" to maintain your security. Entering something like the names of three or four childhood pets will be far easier for you to remember, but almost as difficult for anyone else to guess.

After this, CTI Text Encryption works more or less as youd expect. You type or paste text into the source box and click "Encrypt". The program uses SHA512 to hash the passwords, 256-bit AES (Rijndael) to process the text, and displays the results in the "Encrypted" box. ("Hello world" became "ZNz02G1/x+susprkZONobg==", for example.)

One click then copies the encrypted text to the clipboard, where you can paste it into an email, a forum message, wherever you like. A friend who also has a copy of CTI Text Encryption -- and knows your passwords -- should be able to read what youve said, while everyone else will be locked out.

What you dont get is any option to load, encrypt/ decrypt or save text files directly. You can work around this by, say, opening a text file in Notepad, copying and pasting this into CTI Text Encryption, but thats not as convenient.

There is also one slightly bizarre extra, in the ability to set a font. This is preserved within the message, so whoever is decrypting it will not only see your words, but also their chosen font. Its difficult to see why you would care about this -- and presumably it could introduce problems, if the recipient doesnt have the same font -- but the feature is here if you need it.

CTI Text Encryptionhas a few small issues, then, but in general works very well: its simple, straightforward, and provides an easy way to encrypt small text messages from almost any PC.

Survival guide for data in the wild

The US Congress has passed a bill that removes the NSA's direct input into encryption standards.

According to a report at ProPublica, an amendment to the National Institute of Standards and Technology act removes the requirement that NIST consult with the NSA in setting new encryption standards.

Following the Snowden revelations, NIST had denied that it deliberately weakened encryption standards at the behest of the NSA.

However, that didn't put to rest suspicions that weaknesses such as existed in Dual_EC_DRBG were deliberate NSA contrivances, with RSA singled out for criticism over the random number generator.

Earlier this year, NIST formalised its advice that nobody should be using Dual_EC_DRBG.

Concern over the NSA's involvement also led to an unsuccessful campaign to exclude the agency from IETF crypto research, and a successful one to block RSA key swaps from the TLS standards.

According to Slate, Congress has now passed the amendment that was recommended by the House Science and Technology Committee (Slate also complains that the rest of the bill is mostly toothless).

As Bruce Schneir pointed out last week, users' one source of post-Snowden optimism is that vast dollars haven't yet delivered a special sauce that lets the NSA or its five-eyes partners crack well-implemented encryption.

Hence their continuing reliance either on social engineering, or on various forms of keylogging, to get user data.

Citrix Sharefile will offer metadata encryption to minimise the risk of data leaks in the enterprise.

Citrix Sharefile will offer metadata encryption to minimise the risk of data leaks in the enterprise.

Against the backdrop of the battle of the consumer file sharing systems offering cheap solutions for enterprise, Citrix Sharefile has had to develop a clear roadmap that offers CIOs piece of mind while keeping up with the upgrades and usability employees demand.

Citrix's mobile app, which allows employees to use word documents and sign PDFs while out of the office, entered the Google play store yesterday. It is the result of Citrix's acquisition of Bite Squared last year, and an iPad app will follow. The vendor is now turning its attention to its meta-data encryption service as part of the StorageZone product, which will be deployed in the next few months.

Jess Lipson, founder of ShareFile and Citrix's VP & GM of Data Sharing told ComputerworldUK: "We are going to have a small component that enterprises can install on-premise. It's basically a proxy, all the calls that come from your mobile apps and other maps will flow through that and it will encrypt that data on its way to the Citrix data centre. Citrix is able to run the user interface part of the application in the cloud so are able to do the rapid releases that end users are expecting but we won't have access to that data that's encrypted in our cloud."

Lipson said that some customers have already signed up for the beta rollout in the next few months. He added: "If they are concerned about metadata encryption they aren't going to want me to say who."

Changing markets

Citrix Systems acquired ShareFile in 2011 in an effort to break into the cloud-based data sharing market, but it is still innovating to ensure they have the edge on competition.

Lipson admitted that Citrix's small business space was threatened by consumer clouds like Dropbox, Google Drive and One Drive, and it is turning its attention to specialising in some of the industry verticals.
